摘要： In a navigation system using a bird's-eye view display mode, map data on a plan view map are subjected to a perspective projection conversion to obtain drawing data on a bird's-eye view map. An input of the position of a view point is accepted, and a projection plane for a bird's-eye view is determined so that the display positions of the two points which have been subjected to perspective-projection conversion are coincident with predetermined positions. Alternatively, an input of a scale is accepted, so that the display positions of the two points after the perspective projection conversion are coincident with predetermined positions and the drawing scale is coincident with the input scale. In a further alternative, an input of the projection angle is accepted, and the projection plane is determined on the basis of the projection angle and the position of the view point.

摘要： A map display apparatus for displaying perspective image of a map. The apparatus includes an image display device for displaying the perspective image of the map and a map data storage device for storing map data. Map drawing means is included for preparing map drawing data using the map data and for displaying a perspective image of the map on the display device on the basis of the drawing data. The map drawing means transforms coordinate data of a map into data suitable for display of the perspective image of the map. The data transformation is accomplished by perspectively projecting the coordinate data onto a predetermined projection plane with a view point at a desired position. The projection plane is determined on the basis of two predetermined points in the map data, such as the current position of a vehicle and the destination, so that drawing positions of the two points after the perspectively projecting operation are coincident with predetermined positions.

摘要： A keyless entry system for an automotive vehicle allows operation of a vehicle device or devices without the need for an ignition key or other mechanical keys. A user can simply depress a single push-button or operate another suitable type of switch to activate the system and operate the desired vehicle device to the desired position. The system generally comprises a pocket-portable radio signal transmitter and a controller mounted on the vehicle and associated with the vehicle device. The transmitter has a small, long-life battery and the controller receives electric power from the vehicle battery. Power conservation for both the transmitter and the controller is achieved by activating them for limited periods in response to operation of the manual switch.
